Used in organic synthesis as a photoinitiator in polymer chemistry, enabling cross-linking and curing processes under light exposure. Its derivatives show potential in photodynamic therapy due to light-induced generation of reactive oxygen species. Also employed as a fluorescent probe in biochemical assays for tracking cellular components and monitoring molecular interactions. Exhibits activity in dye-sensitized solar cells as a photosensitizer, improving electron transfer efficiency. Investigated for antimicrobial and antitumor applications owing to its intercalating ability with DNA under photoactivation.
